Microwave-assisted T6 heat treating of aluminium alloy-Al2O3 nanocomposites

Blending ultrafine-grained microstructure with other added reinforcement elements that can provide good strength-microstructural integrity is the primary metallurgical target for any developed composite to exhibit its maximum strength at reduced cost and energy in aerospace application. Such nano-reinforced aluminium alloy composites are processed through addition of nano alumina using powder metallurgy route followed by microwave-assisted T6 heat treatment. Homogeneous nucleation increasing activation grain interface resulted significantly enhanced mechanical properties like microhardness fabricated nanocomposites.
